Interesting ... plenty of opportunity then potentially for the 100 samples to have prediction similarity to the set of published discoveries (for expected or unknown reasons)?

I suppose it will take a few more years of repetition for the challenge to confirm that the problem has been been solved -- but I wonder if a new version of the contest is going to be needed as well? Maybe the model accuracy is now high enough to invert the contest to a form where models generate predictions for randomly selected unknown samples -- and experimental teams are then expected to make observations for those particular sequences over the next two years as part of their otherwise research agenda selected experimental workload?
